context

public ActorContext context()

Description copied from interface: Actor

Stores the context for this actor, including self, and sender. It is implicit to support operations such as forward.

WARNING: Only valid within the Actor itself, so do not close over it and publish it to other threads!

ActorContext is the Scala API. getContext returns a UntypedActorContext, which is the Java API of the actor context.

Specified by:

context in interface Actor

Returns:

(undocumented)

self

public final ActorRef self()

Description copied from interface: Actor

The 'self' field holds the ActorRef for this actor.

Can be used to send messages to itself:

 self ! message
 

Specified by:

self in interface Actor

Returns:

(undocumented)

cluster

public Cluster cluster()

verboseHeartbeat

public boolean verboseHeartbeat()

failureDetector

public FailureDetectorRegistry<Address> failureDetector()

selfHeartbeat

public ClusterHeartbeatSender.Heartbeat selfHeartbeat()

state

public ClusterHeartbeatSenderState state()

heartbeatTask

public Cancellable heartbeatTask()

preStart

public void preStart()

Description copied from interface: Actor

User overridable callback.

Is called when an Actor is started. Actors are automatically started asynchronously when created. Empty default implementation.

Specified by:

preStart in interface Actor

postStop

public void postStop()

Description copied from interface: Actor

User overridable callback.

Is called asynchronously after 'actor.stop()' is invoked. Empty default implementation.

Specified by:

postStop in interface Actor

heartbeatReceiver

public ActorSelection heartbeatReceiver(Address address)

Looks up and returns the remote cluster heartbeat connection for the specific address.

Parameters:

address - (undocumented)

Returns:

(undocumented)

receive

public scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> receive()

Description copied from interface: Actor

This defines the initial actor behavior, it must return a partial function with the actor logic.

Specified by:

receive in interface Actor

Returns:

(undocumented)

initializing

public scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> initializing()

active

public scala.PartialFunction<java.lang.Object,scala.runtime.BoxedUnit> active()

init
